CERAMIC RESIDUE ANALYSIS AND AMS RADIOCARBON DATING OF CERAMIC SHERDS FROM SITE 10Oa275, ONEIDA COUNTY, IDAHO

Three ceramic sherds, 29-88-5, 29-88-6, and 29-92-1, were submitted for ceramic analysis. The Promontory Gray sherds, samples 29-88-5 and 29-88-6, were fragments of a Promontory gray globular-shaped jar that would have measured roughly 18 to 20 cm in diameter and roughly 15 cm in height when intact. This vessel was presumed to have been used as a bone grease rendering vessel and dated between A.D. 1450 and 1650. Both sherds (29-88-5 and 29-88-6) were treated as a single sherd sample. The third ceramic sherd (sample 29-92-1) is a Great Salt Lake Gray sherd, supposedly from a separate vessel. Both ceramic sherd samples were analyzed for pollen, phytolith and starch remains. In addition, organic compounds were extracted from 29-92-1 and submitted for AMS radiocarbon dating.
